“This it is, O king! By the study of that book I am instructed in all magic arts, and can command the assistance of genii to accomplish my plans. The mystery of the Talisman of Borsa is therefore familiar to me, and such a talisman can I make, nay, one of greater virtues.”
“O wise son of Abu Ayub,” cried Aben Habuz, “better were such a talisman than all the watch-towers on the hills, and sentinels upon the borders. Give me such a safeguard, and the riches of my treasury are at thy command.”
The astrologer immediately set to work to gratify the wishes of the monarch. He caused a great tower to be erected upon the top of the royal palace, which stood on the brow of the hill of the Albaycin. The tower was built of stones brought from Egypt, and taken, it is said, from one of the pyramids. In the upper part of the tower was a circular hall, with windows looking towards every point of the compass, and before each window was a table, on which was arranged, as on a chess-board, a mimic army of horse and foot, with the effigy of the potentate that ruled in that direction, all carved of wood. To each of these tables there was a small lance, no bigger than a bodkin, on which were engraved certain Chaldaic characters. This hall was kept constantly closed, by a gate of brass, with a great lock of steel, the key of which was in possession of the king.
On the top of the tower was a bronze figure of a Moorish horseman, fixed on a pivot, with a shield on one arm, and his lance elevated perpendicularly. The face of this horseman was towards the city, as if keeping guard over it; but if any foe were at hand, the figure would turn in that direction, and would level the lance as if for action.
When this talisman was finished, Aben Habuz was all impatient to try its virtues, and longed as ardently for an invasion as he had ever sighed after repose. His desire was soon gratified. Tidings were brought, early one morning, by the sentinel appointed to watch the tower, that the face of the bronze horseman was turned towards the mountains of Elvira, and that his lance pointed directly against the Pass of Lope.
“Let the drums and trumpets sound to arms, and all Granada be put on the alert,” said Aben Habuz.
